Taall whom t mag/cameras Y a subject .of the Emperor ofGermany, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and usefullmprovement in Axle-Collars., of which. the following is a` specification..

My invention relates to. axleinclosing devicesfor spacing purposes and it has particular reference to divided. axle collarsffor positioning electric motors on the wheel axles of electric railway vehicles. Y

The `obj ect of: myA invention; is` to provide a divided axle collar that shall-be particularly light in weight` as well as simple and inexpensive in y construction.

The usual form of divided axle collar comprises two semi-cylindrical castings or pressed metal members that are .fastened to. gether to Vinclcse the axle by suitable clampV ing devices. ln order to permit of longitudinal adjustment of the collar, as a whole, means, such as separate andlongitudinally disposed bolts operating in threaded lugs, are usually provided.

According tofmy present invention, I ,provide a divided axlel collar of pressed-metal construction in which each. half thereof is formed of separate portions arranged in side-byeside relationV withrespect to the axle and secured together` by suitable means which also. permit of the longitudinal adjustment of the collar as a whole, along the axle. The separate portions. constituting each half of the collar are formed from cupshaped. pressed-metaly members that are divided along their central axes. Thus, the assembledhalves of the axle collar may be made of any desiredoverall length by varying the depth of one or both of the cupshaped members.

In the accompanying drawings, Figure 1 is a View, partially in section and partially in side elevation, of a divided axle collar constructedin accordance with my` invention and applied to the vaxle of an electric vehicle; Fig. 2 is a view, partially in front elevation and partially inv section, along the line Il-Il of Fig. 1;.Fig. 3 is a plan` view of one of the pressed-metal. members. Fig. e is a sectional view alongthe line lV--V of Fig. 3; Fig. 5 is a plan view of another of the pressed-metal membersand Fig. ..6.isav

sectional View along the line-z VI--Vll. ofi" Fig. 5.

Referring to Fig. l, a. Wheel 1 is mounted on a suitable shaft or axle 2 4that is adapted.

to.- be driven. by an electric. motor (not shown).` The motor is provided With. a. suitable axle bearing 3 that isinclosed by a portion` 4l:A of thek motor frame. The` axle bearing- 3 is spacedV a predetermined disf tance from the wheel 1 by a divided` axle collar 5. The collar 5 comprises a pair of` substantially identical. half portions which inclose the axle 2 and are securedtogether by means which will hereinafter be described. Each4 half ofthe axle `collar 5 comprises oppositely` disposed portionsl and 7a which are arranged in side-byfside relation along the axle 2. The correspondingv pore tions 6a and 7El of the complete axle collar 5 are. formed from cup-shaped pressed.- metal members 6 and 7 as best shown in Figs.. 3 and 5. The member 6 is pressed from a suitable sheetmetal blank and is formed with two parallel walls 8 8 and two walls 9 9 at riffht angles thereto which are expanded outwardly to form intermediate curved portions Sla-9.a., The walls 8--8 and 9-9 are oppositely inclined .toward each other and are bent at right angles along their inner edges. reform abaseportion 1.0. The base 10 is provided with acentral opening` 11, the diameter of.y which is substantially equal to the diameter of the axle 2,. The straight portions of the wallet) are provided with alined openings12 and with annular depressions 13. surrounding the openings. The member 6 is divided.along its horizontal axis, as indicated by the dotted lines in Fig. 3, t0 form identical `half portions 6a. The pressed-metal member 7 is formed with walls lll-1st and 15-15 similar in contour to the walls 8.--8 and.9--9, respectively, of the member `6. The walls 1%*1ll and 15-15 are oppositely inclined toward each other and are severally contracted to form a cylindrical portion 16 which terminatesin an annular flange 17, as best shown in. Fig. 6. The inner diameter ofthe annular flange 17 is substantially equal to the diameter of the shaft 2. The member 7 is divided along its horizontal axis, as indicated by the dotted linesto form identical half portions 7 a. As best shown in Figs. 1 and 2, the portions 6a and 7a, constituting each half of the axle collar, are secured together, with the Walls 8 and 9 respectivelyV coinciding With the Walls 1.4 and 15 by means of ajoint 19. The joint 19 Y comprises a cylindrical portion 20 and a pair Yio of outwardly extending curved flanges 21. Y

The Iianges121-engage thecurved portions 91van`d'15tL ofthe walls 9 and 15, respectively, and are secured thereto by meansot' rivets 22. The base of the portion (1L 1s provided With'a circular opening 23 that f registers With an opening 24 which 1s provided inthe cylindrical portion of the joint 19. kThe portions-6a and 7a are further securedtogether bymeans of a plate 25 that s is in engagement with the Walls 8 and 14, respectively, and' rivets 26. The 'exterior surface of' the flange'l is provided With a semi-annular Wearing plate 27 of hard fiber `or other similar material which is secured tothe flange by means of rivets 28. The assembled halvesV of the axle collar 5 are clamped together by means of bolts 29 that extend through the openings 12 and nuts 30 in threaded engagement With the bolts. VThe axle collar 5, as a Whole, is positioned on the shaft so that the Wearing plates 27 closely engage. the end of the bearing member 3, by means of positioning boltsl that are in threaded engagement with the openings 24 of the joint 19. The heads of the bolts 30 abut the surface of the Wheel 1, and the axle collarV is maintained in any predetermined Yposition by means of lock nuts 31 coacting With the bolts 30.

From the foregoing, it is apparent that divided axle collars of any desired length may be formed by providing a number of pressed-metal cup-shaped members of varying depth, and suitably combining the pairs of semi-cup-shaped portions.V ln this Way,
